Vinyl records have seen a resurgence in popularity, cherished by music enthusiasts for their unique sound and nostalgic appeal. At Solid-Merch, we are dedicated to providing high-quality vinyl pressings using the Direct Metal Mastering (DMM) technique. In this post, we’ll explain how DMM works and why we have chosen this method for our pressings.

 

History of Vinyl Pressing

The process of pressing custom vinyl records has evolved significantly since its inception in the early 20th century. Initially, records were made using shellac, but vinyl became the preferred material due to its durability and superior sound quality. Over time, the technology for creating vinyl records improved, leading to the development of various mastering techniques, including DMM.


What is Direct Metal Mastering (DMM)?

Direct Metal Mastering is a technique where the audio is cut directly onto a metal disc, typically copper, instead of the traditional lacquer-coated aluminum disc. This method, which emerged in the late 1970s, offers a distinct approach to vinyl mastering, and it’s the technique we exclusively use at Solid-Merch for our custom vinyl record pressings for independent bands and labels.


The DMM Process

The DMM process involves several detailed steps to ensure the production of high-quality custom vinyl records.

  1. Cutting the Master: In DMM, the audio signal is fed directly to a cutting lathe equipped with a diamond stylus. This stylus engraves the audio grooves into a copper-coated disc. The precision of this process helps in accurately capturing the audio details.
  2. Electroplating: After the master is cut, it undergoes electroplating. The copper master is coated with a layer of nickel to create a negative image of the grooves, known as the father. This father is then used to produce a positive image (the mother), which can create multiple stampers.
  3. Manufacturing the Stamper: The stamper is the final negative copy used to press the vinyl records. It’s created from the mother and is mounted onto the pressing machine. The stamper’s grooves mirror the original audio, ensuring high fidelity during the pressing process.
  4. Pressing the Vinyl: The stamper is placed into a hydraulic press, along with a puck of vinyl material. Under heat and pressure, the vinyl is pressed into the grooves of the stamper, creating the final record. The excess vinyl is trimmed off, and the record is cooled and inspected for quality.
